Microsoft have released a Color Applet for the Windows XP Control Panel, which allows you to manage ICC color profiles and ICM 2.0 color settings across the system.

Using the Microsoft Color Control Panel Applet, you can:
• Install and uninstall ICC color profiles
• Inspect, rename, and compare two different color profiles
• View a 3D graphics plot of color profile color gamuts
• Associate color profiles with devices such as printers, monitors, and scanners
• Apply custom color gamut adjustments to one or more displays on the fly
• Set up display calibration reminders at intervals you specify
